In the case of Toledo Pressed Steel Co. v. Standard Parts, Inc., 1938, the U.S Supreme Court was asked to determine whether a patent held by Standard Parts for an automobile leaf spring was valid and infringed upon by Toledo Pressed Steel Co. The lower courts had ruled in favor of Standard Parts, finding that their patent was indeed valid and infringed upon by Toledo's product. However, on appeal to the Supreme Court, it reversed this decision stating that while there may have been some similarities between the two products; they were not identical nor did they function in exactly the same way which is crucial when considering infringement claims under patent law. Furthermore, it found that Standard Part's patent lacked novelty as its design elements were already known within industry circles prior to its application date thereby rendering it invalid.

The dissenting opinion in the case of Toledo Pressed Steel Co. v. Standard Parts, Inc., argued that the majority's decision to uphold a patent on an automobile part was incorrect because it did not meet the standard for novelty and non-obviousness required by patent law. The dissent contended that there were already similar devices in existence at the time of invention, making this particular device neither new nor innovative enough to warrant a patent. Furthermore, they believed that granting such patents would stifle competition and innovation within industries as companies could monopolize basic designs or concepts through broad patents claims. They also expressed concern about potential abuse of power by large corporations who might use their resources to secure unnecessary patents and limit smaller competitors' ability to innovate or compete effectively.
